V5-561G laptop keyboard has dead keys that spread.

The laptop keyboard started being unresponsive to the A key, then spread to the keys Fn, 0, Num Lock, Space, f, J, ;, down arrow and up arrow. I replaced it recently, which fixed the problem for around 2 weeks, and then the problem started again, starting with the Fn and A key. It also spread to 1 and Esc.
I don't damage the keys both accidentally or intentionally.
What should I do?
